|

|

// - It must be disabled on Windows at all times, otherwise the main window becomes

// unresponsive after a few seconds of user interaction (e.g. trying to
|
|
// move it over the desktop). Probably due to the subtle issues around
|
|
// input on this platform (input-queue is global, message-queue is
|
|
// per-thread). Also, this messes considerably the display of the
|
|
// main window when running the executable under Wine.
|
|
//
|
|
// - On Linux/XGL and OSX/Cocoa, this used to be necessary to avoid corruption
|
|
// issues with the GL state of the main window when using the SDL UI.
|
|
// After the switch to Qt, this is no longer necessary and may actually cause
|
|
// undesired interactions between the UI thread and the RenderWindow thread:
|
|
// for example, in a multi-monitor setup the context might be recreated when
|
|
// dragging the window between monitors, triggering a Qt-specific callback
